click on their mobile phones. It supports full-system diagnosis, including engine and transmission, and monitors data in various ways, such as graphs, text, or dashboards. Its one-click I/M readiness function enables users to monitor carbon emissions anytime, anywhere, making it particularly suitable for emission pre-testing during road checks or annual inspections. Injector coding significantly influences automotive emission performance. Uncoded injectors may lead to incomplete combustion and increased emission of harmful gases. TopScan Pro, equipped with 13 commonly used reset functions, including injector coding, ensures the normal operation of the engine, improves fuel efficiency, and reduces harmful gas emissions.” Simon added: “By effectively utilising these technologies, vehicle electronics and engine management systems can significantly reduce automotive emissions, making vehicles environmentally friendly while delivering superior performance.” Advancing vehicle technology For some garages, OEM tools are the only way forward. With this in mind, Maverick Diagnostics is offering garages a subscription-based Dealer Tool Support programme that offers helpdesk support software updates, and troubleshooting guidance for garages using OEM brand tools. Dara Beck from Arwyns Garage commented: “Due to advancing vehicle technology, OEM tools are integral for aftermarket professionals. We've been with Maverick Diagnostics since late 2018, and the team have been very helpful in setting up our OEM tools and licensing. We upgraded to cover more VMs. Maverick Diagnostics can remote-in and assist us with a vehicle where we can work in another vehicle, which saves us time and money.” For more information, visit www.maverickdiagnostics.com Thermal management Nissens Automotive Marketing Manager Jan Zieleskiewicz observed: “Effective engine management covers far more than just the control of the ignition system and exhaust emissions and one of the areas that is sometimes overlooked is the thermal management requirements of the engine. “Every vehicle powered by a combustion engine, and that therefore includes hybrids, needs effective thermal control of the engine, which means not only cooling to prevent overheating, but also means the quickest possible build up in temperature to reach and then be maintained at the optimum level. Naturally, the combustion process causes very high temperature ranges, exposing the engine’s block and its equipment to an extremely high thermal stress. Furthermore, turbocharged combustion systems also need sufficient air cooling to obtain the right charge performance, and manual gearboxes, as well as power transmission units all need active engine management to ensure each component is operating at its design temperature to ensure the optimum performance of the whole powertrain.” Jan added: “To achieve these sometimes-conflicting objectives increasingly requires electrical sensors, which itself reflects the growing number of electronically controlled components utilised in modern vehicle design. As a result, Nissens added engine coolant and oil temperature sensors to its range of thermal management solutions.” Essential data Sensors play a key role, as Becca Knight, Marketing Manager at Niterra UK, said: “Sensor technology has paved the way for new heights of precision, power, and economy from today’s engines, often working in harmony with traditional ignition components and just as critical to a wellrunning engine. “Timing is the determining factor to keeping an internal combustion engine running with accuracy and efficiency. In a four-stage combustion sequence, camshaft and crankshaft sensors for example provide the ECU with positioning and timing data for exact fuelling and ignition. “Exhaust pressure sensors play a significant role in engine optimisation. They provide the ECU with pressure data that can relate to various connected exhaust systems including exhaust gas recirculation valves, turbos, and emissions filter units which may now be found on either a petrol or diesel vehicle. The newest NTK range encapsulates different sensor types such as differential pressure and high-pressure sensors and boasts application coverage of more than 70% of the UK parc at the launch in 2023.” Becca added: “Essential data from sensors works in harmony with the critical ignition from traditional combustion components. They are so finely matched that if engine timing is off by a few milliseconds the customer can experience rough running and engine warning lights, and this is why reliable sensors make all the difference.” For more information, visit: www.ngkntk.com/uk Important subjects To keep technicians up to date on sensors, DENSO has published a pair of leaflets, the first covering exhaust gas temperature sensors (EGTS), with the second looking towards mass air flow (MAF) sensors. DENSO Europe Pan European Strategic Marketing Manager Fatiha Laauich observed: “Both publications follow a similar format and begin by describing the role of the 36 AFTERMARKET MARCH 2024 VEHICLE ELECTRONICS AND ENGINE MANAGEMENT www.aftermarketonline.net Below: TopScan Pro from TOPDON Modern vehicles rely on electronic systems; Thus, it is important for technicians to identify and resolve engine and emission system issues ”
